(2) With disconnect switch option
(3) mm²/phase
Note: To prevent control malfunctions, do not run low-voltage wiring (<30V) in conduits with conductors carrying more than 30 V.
All wiring must comply with
national electrical regulations.
Electrical characteristics and other
unit electrical data are on the unit
nameplate. Specific electrical
schematics and connection
diagrams are shipped with the unit.
Use copper conductors only. Unit
terminals are not designed to accept
other types of conductors. Failure to
do so may cause damage to the
equipment.
Do not allow conduits to interfere
with other components, structural
members, or equipment. All
conduits must be long enough to
allow compressor and starter
removal.
